Half Day Cruise to Benagil Caves

About

This four-hour boat trip runs out of Vilamoura and loops west along the Algarve coast to the Benagil sea cave. It's the classic Algarve postcard shot — the domed cave with the skylight hole and the sand patch inside — and the half-day format means you see it without burning the whole day. The boat usually stops for swimming if the swell allows, and you pass a string of other caves and rock arches on the way. Sixteen reviews on the booking platform all rate it five stars, which is tight enough to mean the crew delivers. Morning departures tend to catch better light inside the cave, though afternoon works if your schedule is jammed. Wear shoes you can get wet and bring a towel if you plan to swim.
